FeLV is the number-one deadliest disease among domestic cats. Vaccination is the only defense against this virus.

Feline leukemia virus (FeLV) suppresses the immune system and results in various types of cancer and other chronic and debilitating diseases in cats. Signs of infection include gum disease, vomiting, diarrhea, weight loss, decreased appetite, lethargy, anemia and infections that are resistant to standard treatments. Although cats can remain apparently healthy for months or even years following infection, once signs begin, they are difficult to impossible to treat successfully.

FeLV is transmitted through direct contact with an infected cat, such as by mutual grooming, fighting or playing, or by sharing a food or water dish or litter box with an infected cat. The virus can spread from an infected mother cat to her kittens through the placenta or during nursing. Bite wounds are an especially effective method of transmission because there is a high level of virus in salvia of an infected cat.

Affected cats not yet showing signs of illness may shed the virus and be infective to other cats, making it vital never to bring a new cat into your household without testing for FeLV. Many cats appear to be perfectly healthy at the time of diagnosis another reason every cat should be tested for FeLV. Because the disease's lengthy incubation period may cause an infected cat to test negative for some time after exposure, the cat should be retested six weeks after possible exposure.

Even though a vaccine against feline leukemia virus has been available to cat owners since 1985, FeLV remains the leading infectious cause of illness and death in domestic cats. At this time, vaccination and preventing exposure to possible carriers are the only defenses against this devastating disease.

FeLV vaccination consists of two initial injections about three weeks apart with yearly boosters thereafter. It is highly recommended that cats be tested for FeLV before vaccination.

I had an FeLV+ cat who was the joy of my life. We took him in at 2 weeks old as an abandoned kitten and cared for him until the disease took over a year and half later. In the time frame, and since then, I have been studying Feline Leukemia in the hopes to advocate to the public that just because your cat is infected does not mean that you should put it to sleep. I am working on a campaign done through a website (yet to be launched) called FeLV Advocate (www.felvadvocate.com). This website explains all about what feline leukemia is, and methods that through veterinary research I have discovered COULD help to keep your leukemia cat living longer and with other cats in the household. I feel that these creatures were put on this earth for a reason, and we do not have the priviledge just because we are human to decide what lives and what dies. These cats are living breathing beings and they should be given a chance at life.
I believe these cats could even help other diseased people, such as cancer victims and cardiac disease patients, to recover better because these animals have the ability to understand what they are going through as opposed to a family member that is perfectly healthy.
I believe Leukemia cats need a new voice. I vowed on my leukemia cat, Leo's deathbed that I would tell his story and I would be the that voice.
